"One of the goals of the roster for this game and moving forward is to create competition at each position," Klinsmann said. "There are many players who are established as well as many players who will get opportunities, and we want there to be a healthy contest for spots on the roster. We will get a good look at where each player is as quickly as we can."

The game against El Tri on Wednesday in Philadelphia is a rematch of the Gold Cup final in June, a flop that led to Klinsmann's hiring.

Klinsmann, one of the greatest players Germany has ever produced, transformed a stodgy German squad in his brief stint as a coach of his native country's national team, and U.S. Soccer hopes he can do the same here. He spent much of his introductory news conference talking about player development and is wasting little time seeing if there are other players out there who could help the U.S. when World Cup qualifying begins next year.

Under-20 World Cup: Mexico held England to a 0-0 draw to secure a spot in the second round of the Under-20 World Cup in Cartagena, Colombia, leaving the English relying on results in other groups to remain in contention at the tournament.

Argentina defeated North Korea 3-0 in Medellin earlier to top Group F with seven points, three more than Mexico. England ended with three points after three scoreless draws but could still advance if it is among the four best third-place finishers from the six groups. North Korea was eliminated with one point.

Mexico had its best chance with a penalty in the 14th minute, but striker Taufic Guarch had his shot saved by England goalkeeper Jack Butland. The penalty was awarded after England defender Reece Brown's foul on Erick Torres inside the area.

In other U-20 action, Philippe Coutinho's two goals led Brazil to a 4-0 win over Panama and a place in the knockout stage, and Mohamaed Ibrahim scored three goals for Egypt in its 4-0 win over Austria.
